SHERIDAN — A Sheridan man has reached a cold plea agreement with prosecutors.

According to a Dec. 17 4th Judicial District Court filing, Colby Streeter agreed to plead guilty to two counts of sexual abuse of a minor. Streeter is accused of sexually abusing two preteen girls over the course of two years.

According to an affidavit of probable cause, the abuse was discovered after one of the victims told a friend. The friend then told a school counselor and law enforcement launched an investigation.

Court documents also indicate that the victims had told another adult, but that adult had not reported the crime to law enforcement. The documents also state that Streeter submitted to a polygraph test, which was administered in Gillette in May. Streeter was confronted after law enforcement officers observed signs of deception. Streeter initially denied the allegations, but then claimed at least one of the girls had initiated the inappropriate contact.

Streeter originally entered a not guilty plea to the charges. A change of plea hearing has not yet been scheduled.

Streeter faces up to 20 years in prison, a fine of $10,000 or both for each count.
